British woodlands and forests are often located on sites and in regions that are marginal for agriculture; many are at high elevations and exposed, with short growing seasons. Wherever forests are located, site and climatic conditions must dictate species choice in forest management. This book provides a detailed guide to the biological suitability of different sites and soils for all important native trees and the most extensively used exotics. Apart from physical difficulties such as steepness and stoniness, forest soils also frequently have problems associated with them. They can be waterlogged or drought-prone, suffer from extremes of acidity or alkalinity, or have compacted layers. The book provides information on species' suitability for different purposes. It includes details of species' origin and introduction (where applicable), as well as their climatic and soil requirements and other silvicultural characteristics. Information about provenance, yield and timber is also provided. Fully updated throughout, this 3rd edition puts more emphasis on species suitable for changing climatic conditions, with accounts of several species that may become more prominent in British forests: including several silver firs, hickories, eucalypts, spruces, poplars and wingnuts. The book concludes with simple keys for identifying the trees most likely to be encountered in British forests. It is an essential resource for students, researchers and forestry professionals.

As forests decline in temperate and tropical climates, highly-developed countries and those striving for greater economic and social benefits are beginning to utilize marginal forests of high-latitude and mountainous regions for resources to satisfy human needs. The benefits of marginal forests range from purely aesthetic to providing resources for producing many goods and services demanded by a growing world population. Increased demands for forest resources and amenities and recent warming of high latitude climates have generated interest in reforestation and afforestation of marginal habitats in cold regions. Afforestation of treeless landscapes improves the environment for human habitation and provides for land use and economic prosperity. Trees are frequently planted in cold climates to rehabilitate denuded sites, for the amenity of homes and villages, and for wind shelter, recreation, agroforestry, and industrial uses. In addition, forests in cold climates reduce the albedo of the earth's surface in winter, and in summer they are small but significant long-lived sinks for atmospheric carbon dioxide. Finally, growth and reproductive success of forests at their geographic limits are sensitive indices of climatic change. As efforts to adapt forests to cold climates increase, however, new afforestation problems arise and old ones intensify. Austral, northern, and altitudinal tree limits are determined by many different factors. Current hypotheses for high-latitude tree limits are based on low growing-season temperatures that inhibit plant development and reproduction.

Plantation Silviculture in Europe provides an up-to-date, succinct, and comprehensive overview of current European plantation forestry practices. Recognising that plantation silviculture today is no longer largely a question of how to grow large-scale industrial plantations, the authors have included chapters describing other, more diverse reasons for establishing trees. Forestry practices are set in the context of the science behind them and their environmental, social and policy frameworks. Concise and clear, this will be essential reading for forestry students and professionals alike. - ;As pressures to preserve natural forest resources have increased, plantation forestry and its study have gained in importance. Plantation Silviculture in Europe is an up-to-date, timely, and comprehensive exploration of the principles that underlie the planting and maintaining of forest resources. Based on the excellent reception of Savill and Evans' Plantation Silviculture in Temperate Regions (OUP, 1986), which was largely UK-based, the inclusion of two European authors ensures that the scope of this new book extends across the entire continent. Plantation Silviculture in Europe provides a thorough overview of the central aspects of conventional plantation forestry, covering site preparation, choice of species, establishment and maintenance, nutrition, spacing, thinning and pruning, and protection. In addition, it acknowledges the changing emphasis and increasing diversity of contemporary forestry, and includes chapters on community woodlands, urban forests, plantings for amenity and sport, and energy crops. Throughout, an attempt is made to set practices in the context of the ecological and biological forest processes which underpin them. Plantation Silviculture also incorporates discussion of the many environmental, social and policy issues that surround forestry today. Concise and clearly written, this will be essential reading for graduate and undergraduate forestry students and forestry professionals alike. Likely to become the standard text throughout Europe, it also contains much material of relevance to foresters in North America, East Asia, and Australasia. -

The Twentieth Edition takes The Agricultural Notebook into its third century; it has been thoroughly revised and updated to reflect the considerable changes in agricultural and rural practices and policies which have taken place since publication of the previous edition. The book is divided into four parts: Crops, Management, Animal Production, and Farm Equipment. New sections added to this edition include: 1) A Marketing Perspective on Diversification, 2) Organic Farming, and 3) Farming and Wildlife. Since the first edition was compiled by Primrose McConnell in 1883, The Agricultural Notebook has become established as the standard work of reference for all those in the farming industry. With each edition it has evolved and changed in such a way as to provide agricultural scientists, students of agriculture and related subjects, farmers, farm managers and land agents with an abundance of current information on all aspects of the business of farming. Many comments received from lecturers and students who have used previous editions of the book have been taken into account in producing the twentieth edition. The thirty contributing authors have fully updated chapters, a new clearer layout has been adopted and much new information is included in easy-to-use tables and figures. The Agricultural Notebook is an essential purchase for all students of agriculture, countryside, and rural studies. Professionals such as farmers, land agents, agricultural scientists, advisers, suppliers to the agriculture industry and all those with a connection and interest in the agricultural community will find a huge wealth of information within the book’s covers. All libraries within universities, colleges and research establishments where agricultural and rural sciences are studied and taught should have multiple copies of this important new edition on their shelves.

Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.
